• Web3 应用程序后端和 API
• 智能合约的部署与交互
• 区块链数据查询与分析
• 开发和测试环境

WebSocket (WSS) 端点

Quicknode 的 WebSocket 端点通过针对不同用例和性能要求进行优化的持久连接，提供实时区块链数据流。

wss://your-endpoint.quiknode.pro/auth-token/

最适合：

• 需要实时价格数据源的DeFi应用
• 区块链浏览器和分析仪表盘
• 交易监控与确认追踪
• 智能合约事件监听

WebSocket (WSS) 限制

信贷使用情况

Different methods consume different amounts of credits: View Polygon API credit costs →

Flat Rate RPS

Flat Rate RPS is a billing option that provides predictable monthly costs for Polygon endpoints. Instead of metering individual requests and charging with API Credits, you pay a fixed monthly fee based on your configured request capacity. Your bill stays the same each month regardless of actual usage.

You can check the Flat Rate RPS documentation to learn more.
